A hybrid electromagnetic-triboelectric nanogenerator(E-TENG)amalgamates the merits of electromagnetic generator(EMG)and triboelectric nanogenerator(TENG)

boasting the ability to generate high voltage

operate high current

and operate across multiple frequency bands.It can harvest energy from natural vibrations such as human movement

biological motions

ocean waves

and wind

and convert the energy into electrical energy. It is expected to address the technical challenges of distributed

continuous self-power supply for wearable devices and self-powered sensing systems.Advantages of the structural design and sensing principles of E-TENG in broadening the bandwidth for low-frequency energy harvesting and enhancing energy conversion efficiency are analyzed.Furthermore

the applications of E-TENG in self-powered sensing

monitoring

and wearable devices are reviewed.Finally

the future development of E-TENG is reviewed and forecasted.
